Zsolt Tóth created HIVE-13626:
---------------------------------
Summary: Unable to cancel certain queries [Spark Branch]
Key: HIVE-13626
URL: https://issues.apache.org/jira/browse/HIVE-13626
Project: Hive
Issue Type: Bug
Components: Spark
Environment: CDH5.7 single node docker
Reporter: Zsolt Tóth
To reproduce:
1. Submit a query to Hive through JDBC
2. Cancel (almost) immediately
For the query _SELECT DISTINCT a FROM test_ the Hive log says:
"java.lang.Exception: Failed to submit Spark work, please retry later" ...
"Caused by: java.io.IOException: java.lang.InterruptedException". After I call
close() on the statement and the connection, the application changes to
FINISHED/SUCCEEDED state (as expected).
However, for the query _SELECT a FROM test order by a_ Hive log says:
"org.apache.hadoop.hive.ql.metadata.HiveException: Failed to create spark
client." ... "Caused by: java.lang.RuntimeException:
java.lang.InterruptedException". Calling close() seems to have no effect, the
yarn application is stuck in RUNNING state.
If I cancel the second query later (e.g. after 10 secs), the application closes
with FINISHED/SUCCEEDED (as expected).
Code snippet:
{code:title=Bar.java|borderStyle=solid}
final Statement st = connection.createStatement();
new Thread() {
@Override
public void run() {
sleep(100);
st.cancel();
}
}.start();
ResultSet r = null;
try {
// r = st.executeQuery("SELECT DISTINCT a FROM test");
r = st.executeQuery("SELECT a FROM test order by a");
} catch (SQLException e) {
close(r);
if (st != null) {
st.close();
}
if (connection != null) {
connection.close();
}
}
{code}
